USB Docking is very interesting indeed...Sigma wants to get rid of the "poor QC " stigma. Which in my opinion, they already did it with the 85mm f1.4 (at least my copy is as good as my other two L primes).

I've been eyeing the 120-300 for quite some time, but have been nervous about focus performance compared to the Canon 300 2.8. Anyone used the previous Sigma 120-300? How does it perform? This new version could be very tempting for football season...

70-300L120-300/2.8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAArgh decisions.I can probably console myself with the 70-300L being more "walkaround", which I do a lot when birdhunting. Although i would very much like a 300/2.8, and if that 300/2.8 comes in black with an extra 120-299mm as well...

You bet the 70-300L is more "walkaround". Compare the weight!70-300L 1050g120-300/2.8 2950gEF 300 f/2.8II 2400gOnly Mr Muscles would consider the Sigma as a walkaround. Wouldn't it be cool if the Sigma weighed in at a less punishing weight?

I find it fascinating that an upgrade on the Sigma 120-300mm f/2.8 DG OS HSM has happened so quickly. The previous model of the Sigma 120-300mm f/2.8 DG OS HSM was almost there for me, just lacking very slightly in some key performance areas.

As people are saying "Sigma do listen", there's a big chance I'll pick up this lens. If the required performance is there, my EF 300 f/2.8is could be headed for retirement. Think about it, a 120-300 f/2.8 zoom makes a pretty compelling case, especially if the critical areas of IQ and AF speed and consistent build quality cross into premium territory.

Liking the looks of the 35 1.4 lens. Right now I'm considering picking up the Sigma 30mm f1.4 (which is a fantastic lens), but it is crop only. If, a few years down the line I upgrade to FF, I'd have to sell. If this lens is under $800, I can have a great 50mm equivalent for current crop camera (approx 50) and even on full frame a 35mm looks awesome. I am excited to see some samples.

Nice! A fast 35mm alternative that (has AF and) doesn't break the bank Sigma may probably change their 50mm and 85mm to look like these new lenses, they did change the paint on the 50 back when the 85 came out.I'll probably wait for those if I go the 85 route than the 135L

I hope the new Sigma 120-300 f2.8 OS is an improvement over their last attempt. At min focus distance, I couldn't see much focal length difference between my 70-200 f2.8 L IS II. So I sold the Siggi...what was the point of all that extra weight, bulk and slower AF system....oh and the AF was fairly fast, but quite erratic. Certainly the best I've seen from Sigma so far, but way off the mark set by Canon's finest.
